 Does the 3/8" connector have a terminal indication next to it? That might help with identification.

If you have a good ground (Engine/chasis to the alt. housing), a good connection to the battery, and the alternator is good, you should be charging in most cases. In your case this seems not be so. I ran into a similar situation with a Nissan, which required an exciter field 12+ connection.

If you are certain that the terminal is not for the charge indicator I would try the following: First ground the terminal, and check if the unit charges. If no effect, then energize this terminal with 12 volt, but with a lamp in between, so your current is limited. What we are trying to do here is figure out if the terminal is a ground connection, or the exciter field connection.

Note: if you apply 12 volt to the charge indicator terminal, you will most likely destroy the pull down diodes.

Good Luck!
